They don't ... they have DDR3 memory attached to the ASICs / FPGAs.  If you look on the Bitmain site, you can see that the device is a) twice the size of their other miners and b) is about the hash equivalent of 4x 580's.  If you consider the 800 watts of draw, it uses more Watts/MH than a rig with 4x 580s.  About the only attractive thing about it is the price ... $800.


180 Mhash/sec is at least 6 RX 470/480/570/580 even with BIOS straps and all other optimizations. (widely reported in the 28-30 Mhash range for best optimized cards, sometimes a bit less).
It's also a HAIR less than 6 x GTX 1070 (31-32 Mhash common numbers, rarely under 31).

Power usage is pretty much a tossup with a well-optimized 6 card rig - bit higher than the Nvidia option, right around the same vs the AMD option.

The size IS interesting, and has led to some speculation that it's somehow a GPU rig - but the PRICE makes it unlikely to be GPU based.


You're right of course.  I'm not sure why my brain settled on 4x when 180/30 is clearly 6x.  The only thing close to 4x would have been Vega64's.

Hello,

How can I set fixed fan speed on AMD cards with claymore? -tt 40 -fanmin -70 -fanmax 90 doesn't work? What am I doing wrong?

Read the readme. -tt -40

How big should the pagefile be for 13 GPU's?

You're trying to achieve a temperature that's impossible during mining, so your fan with -tt 40 will probably always work with full speed. Increase the temperature to somewhat like 80 and see then how it goes.

Do not forget to also set the parameter -tstop.

11.6 is no go for me, I tested it today and after 4 hours crashed a rig with four AMD GPUs, on another AMD rig 11.5 is up and running since days. Of course same settings, same OC, etc etc

Maybe ignorant question, but how are the ASICs going to work? I thought the whole point of DAGs was to prevent ASICs. How do the ASICs fit the DAG file on their chips affordably?

Its not actually an ASIC, its FPGA board

https://bitcointalk.org/index.php?topic=2182826.0

Ethereum ASICs are about to be released onto the market, I hope that there's a fix to the algo to let GPU miners still continue mining.

We are pleased to announce the Antminer E3, world's most powerful and efficient EtHash ASIC miner. Ordering limit of one miner per user and not available in China. Limited stock, order here now.

As for now Ethash ASIC miner have no advantages to make GPU mining impossible. Hashes per watt are pretty the same. Hashrate is comparable to GPU farm. So today Ethereum authority decided NOT to emergency fork.

is any XVG pool online?  Shocked
when we can continue to mine in dual XVG?

After many hours it seems that our pool has returned to synchronize entire blockchain, mining works again, we will see what happens now with the fork.

11.6 works very well. I'm running with RX580 cards on ethOS 1.3.1.

I have a 5 x RX570 on spread across two rigs.  Since upgrading to 11.6, my GPUs randomly lose 10% of hashing power.  After a few minutes they return to normal.  They don't do it all at once, it's just a random one at random times.  I moved back down to 11.2 and the power loss disappears.  Anyone else have this issue?

11.6 Hashrate very stable in my rig, RX580, ethOS 1.3.1

How does the miner apply no dev fee to 3GB cards when it’s mixed with other cards in the system?

I have:
GTX 1060 3GB
GTX 1060 6GB
EthOS 1.3.1 (claymore 11.6)

How do I verify that no dev fee is being applied to the 3GB card?

Oh. Guess it’s only for win10. Lame. Stupid not to have the same conditions for something like this between the win/Linux versions.

Guess I’m back to ethminer in ethos since it gets the same hashrate and it’s free...

.. but you are missing something very important .. network hashrate .. when ASIC become available the network hasrate will spike .. as ASICs are very cheap ... so your profit will fall gravely

On Windows, I'd go with either the blockchain driver or something around 17.11 (whatever the first WQHL version is after they added "large page" support to the mainline drivers).

On LINUX, 17.50 seems a lot more stable than the blockchain drivers, but you have to modify one of the driver modules to get ANY support for undervolting or underclocking the core.

The E3 is NOT going to "spike" the total network hashrate for Ethereum or the other ethash coins.

It will take about 2 MILLION of those units built and operating JUST TO MATCH THE EXISTING HASHRATE.

They aren't shipping 'till mid-July timeframe.

In the almost 2 YEARS since Bitmain introduced the S9 (which was a LOT more efficient than anything else available for months, and STILL is the most efficient SHA256 miner that is shipping) they might have sold a little over ONE MILLION of them (total SHA256 network hashrate says up to 2 million, but you also have to factor in the Avalon 721/741 sales, the eBang sales, sales of whatever miners with Bitfury chips have been built, however much hashrate LW.COM has on it's internally-built miners, and at least one "smaller fry" mining operation I know of that is using their own chip).

The E3 will push network hashrate - but it's NOT going to be a "spike", there is too much EXISTING hashrate from mining rigs that are the SAME OR BETTER efficiency than the E3 announced specs.


It's a lot closer to the situation in Scrypt mining when Bitmain introduced the L3 - which STILL hasn't managed to push all "older rigs" out of profitable service if you have cheap enough electric and has a LOT of competition helping it TRY to push A2/Titan/Alcheminers out of profitability.

ETHEREUM ASIC-PROOF?
In order to make this debate a little bit more organized, pipermirriam have made a GitHub poll asking whether Ethereum should be hard forked in order to render Ethereum ASICs obsolete.
